<p>The winding equipment for winding yarn, tape or wire-shaped material comprises a bobbin shaft carrying a rotatably fixed armature plate, which is in magnetic, adjustable driving connection with a plate carrying permanent magnets and fixed on the shaft of the driving motor, the adjustment thereof resulting by a thread tension regulating device with a dancing arm carrying a dancing roller. In this connection, the motor or the shaft thereof carrying the permanent magnet plate is supported relative to the bobbin shaft carrying the armature plate radially displaceable as a function of the rotating motion of the dancing arm on the frame of the winding equipment. Owing to this radial displacement of the plates generating the driving connection, relative to each other, not only is the induced magnetic field changed in the simplest manner, but, in addition, the two plates can be arranged with the slightest air gap between each other, which, accordingly, allows for the utilization of small permanent magnets to secure a sufficient magnetic driving connection between the two plates.</p> |
